MATLAB - Matrix Multiplication. Consider two matrices A and B. If A is an m x n matrix and B is an n x p matrix, they could be multiplied together to produce an m x n matrix C. Matrix multiplication is possible only if the number of columns n in A is equal to the number of rows n in B.

That is, A*B is typically not equal to B*A. If at least one input is scalar, then A*B is equivalent to A.*B and is commutative. C = mtimes (A,B) is an alternative way to execute A*B, but is rarely used.

23 Feb 2011 “Element-wise” matrix vector multiplication in matlab · Multiply each matrix in a list of matrices against corresponding vector in list of vectors. 31 Jul 2004 A Matlab function mxmuleps has been programmed to reveal Matlab's roundoff threshold for matrix multiplication. This is smaller than eps, the  MATLAB performs those loops for you, so you can write "x times A times x transpose" rather than writing matrix-vector multiplication functions.

Matrix multiplication is not universally commutative for nonscalar inputs. That is, A*B is typically not equal to B*A. If at least one input is scalar, then A*B is equivalent to A.*B and is commutative. C = mtimes (A,B) is an alternative way to execute A*B, but is rarely used. Accepted Answer: madhan ravi.
